The present invention relates to a compound for inhibiting activities of BTK (Bruton's tyrosine kinase) and/or JAK3 (Janus kinase 3) kinases, a pharmaceutical composition thereof, the use thereof in the manufacture of a medicament, a method of using the compound in inhibiting BTK and/or JAK3 activities and a method of using the compound in the treatment and/or prevention of BTK- and/or JAK3-mediated diseases or disorders in mammals, especially in humans.

BACKGROUND ART

Protein kinase is one of the largest families in human enzymes, and more than 500 kinds of protein kinases have been identified in the human body to date. These protein kinases modulate the activities of particular proteins by transferring phosphate groups to the proteins, and then control complex signaling pathways. Aberrant activities of protein kinases are correlated with many diseases including cancers, autoimmune disorders, and so on. Because of the essential role of protein kinases in signaling pathways and the correlation between the kinase activities and many diseases, kinase inhibitors have now become a hot topic for the research and discovery of new chemical entities.

BTK (Bruton's tyrosine kinase) is a non-receptor tyrosine kinase of TEC family. BTK is an essential media of B cell receptor (BCR) signaling pathway and it is a key modulator of early B cell development, and activation, signaling and survival of mature B cells. Thus, BTK inhibitors can be used for treating diseases associated with aberrant activation of B cells, for example, autoimmune diseases including rheumatoid arthritis and systemic lupus erythematosus, etc. The efficacy for treating autoimmune diseases by BTK inhibitors has been preliminary demonstrated in the preclinical animal models (Honigberg, L. A. et al, Proceedings of the National Academy of Sciences of the United States of America, 2010, 107, 13075-13080). Besides B cells, there are experimental evidences showing that BTK also takes part in the signal pathways of monocytes, macrophages, neutrophils and mast cells. BTK inhibitors can depress FcγR-induced release of cytokines including TNFa, IL-1β and IL-6, from monocytes and macrophages, and can also reduce the FcγR-induced degranulation of mast cells (Chang B. Y. et al, Arthritis Research & Therapy, 2011, 13, R115).

The B cell receptor (BCR)-mediated signaling pathway is vital to the survival of many lymphomas. As a key kinase in the BCR pathway, BTK is therefore a potential therapeutic target of lymphomas. In clinical trials, BTK inhibitors show significant effects in the treatment of chronic lymphocytic leukemia (CLL). BTK inhibitors also exhibit significant effects on other lymphomas such as diffused large B-cell lymphoma and mantle cell lymphoma, etc. (Buggy, J. J. et al, International Reviews of Immunology, 2012, 31, 119-132).

Janus kinases are essential tyrosine kinases for modulating the cellular function of lymphatic and hematopoietic cells. Janus kinases include four known members, which are JAK1, JAK2, JAK3 and TYK2, respectively, and wherein JAK3 (Janus tyrosine kinase 3) is mainly expressed in lymphocytes and natural killer cells. JAK3 is constitutively bound to the common γc chain, which is a common receptor subunit for IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21 (Ghoreschi K. et al, Immunological Reviews, 2009, 228, 273-87). These cytokines, mediated through JAK3, are essential for the proliferation, differentiation and functions of lymphocytes. The function loss of the JAK3 kinase will result in the immunodeficiency of both human and mice. Because of the essential role of JAK3 kinase in the immune system, JAK3 kinase is a very attractive target for the treatment of immune-associated diseases, for example, autoimmune diseases like rheumatoid arthritis or allograft rejection in the patients with organ transplantation. Selective JAK3 inhibitors show significant efficacy in the clinical trials of rheumatoid arthritis.

In addition to the individual efficacy of BTK inhibitors and JAK3 inhibitors, simultaneously inhibiting both BTK pathway and JAK3 pathway will potentially have synergetic effects in clinical application. For example, via experiments, Cetkovic-Cvrlje M et al prove that the combination of using BTK and JAK3 inhibitors may improve the survival rates of animals in Graft-Versus-Host Disease (GVHD) models (Cetkovic-Cvrlje M. et al, British Journal of Haematology, 2004, 126, 821-827).

Therefore, it is necessary to develop novel compounds aiming at BTK and/or JAK3 pathways, wherein the novel compounds show good efficacy and can be orally available, which also exhibit pharmacokinetic properties favorable to the therapeutic applications and show sufficiently low toxic and side effects in vivo.

Step 4: Preparation of N-(cis-4-((2-((1-methyl-1H-pyrazol-4-yl)amino)thieno[3,2-d]pyrimidin-4-yl)amino)cyclohexyl)acrylamide

The product obtained in step 3 (54 mg, 0.162 mmol) and 1-methyl-1H-pyrazole-4-amine (23 mg, 0.244 mmol) was dissolved in 1,4-dioxane (2 mL). The pH of the reaction solution was adjusted to 5 with trifluoroacetic acid, and the reaction mixture was reacted at 90° C. under microwave irradiation for 0.5 hours. The reaction solution was cooled to room temperature, and adjusted to pH 8 with IN solution of sodium hydroxide. The resulting mixture was extracted with ethyl acetate (10 mL×3), and the organic phase was dried over anhydrous sodium sulfate, concentrated under reduced pressure, and purified by silica gel column chromatography (eluent: dichloromethane/methanol=10:1) to give a pale yellow solid (32 mg).

Example 57 Preparation of N-(cis-4-((2-((1-methyl-1H-pyrazol-4-yl)amino)furo[3,2-d]pyrimidin-4-yl)amino)cyclohexyl)acrylamide

Step 1: Preparation of cis-N¹-(2-chloro-furo[3,2-d]pyrimidin-4-yl)cyclohexyl-1,4-diamine

2,4-Dichloro-furo[3,2-d]pyrimidine (188 mg, 1 mmol) was dissolved in dichloromethane (5 mL), and dropwise added to a solution of cis-1,4-cyclohexanediamine (456 mg, 4.0 mmol) in dichloromethane (10 mL). The reaction solution was stirred at room temperature overnight, and then concentrated. The residue was added with water (20 mL), and extracted with ethyl acetate (20 mL×3). The organic phase was dried over anhydrous sodium sulfate, concentrated under reduced pressure, and was purified by silica gel column chromatography (eluent: n-hexane:ethyl acetate=1:1), to give a pale yellow solid (140 mg). Yield: 52.6%. MS (ESI, m/z): [M+H]⁺: 267.1; ¹H-NMR (300 MHz, CD₃OD): 8.01-8.00 (d, 1H, J=2.1 Hz), 6.78-6.77 (d, 1H, J=2.1 Hz), 4.24-2.22 (m, 1H), 3.07-3.03 (m, 1H), 1.91-1.66 (m, 8H).

Step 2: Preparation of N-(cis-4-((2-chloro-furo[3,2-d]pyrimidin-4-yl)amino) cyclohexyl)acrylamide

The product obtained in step 1 (120 mg, 0.45 mmol) and triethylamine (188 μL, 1.36 mmol) were dissolved in dichloromethane (20 mL), followed by the addition of acryloyl chloride (53 μL, 0.54 mmol). The reaction solution was reacted at room temperature overnight.

Test example 5 Type II Collagen-Induced Arthritis (CIA) Model in DBA/1J Mice

The CIA model is a widely-used animal model in the study of drugs for the treatment of rheumatoid arthritis in human. The experimental animals used in this experiment are DBA/1J mice (male, 6 to 8 weeks of age, purchased from Shanghai Silaike Laboratory Animal Co., Ltd., China). Mice were housed in an IVC system.

In order to induce the mice CIA model, a bovine type II collagen (CII) (purchased from Chondrex company, No.: 20022) solution was emulsified with the same volume of complete Freund's adjuvant (CFA) (purchased from Sigma-Aldrich, No.: F5881) using an electronic homogenizer to prepare an emulsion. Then, 70 μL of the prepared emulsion was intradermally injected into the base of the tail of the mice as a primary immunization. Three weeks after the primary immunization, one booster immunization was carried out. A bovine type II collagen solution was emulsified with the same volume of incompletely Freund's adjuvant (IFA) (purchased from Sigma-Aldrich, No.: F5506) to prepare an emulsion, and then 70 μL of the prepared emulsion was intradermally injected in a single point into the hind back to complete the immunization. According to the following criteria, Mice were evaluated for the severity of arthritis using an established scoring system ranging from 0 to 4 (0 score: no evidence of edema or swelling; 1 score: mild edema and redness confined to the ankle joint or tarsal; 2 scores: mild edema and redness, from the ankle joint to the tarsal; 3 scores: moderate edema and redness, from the ankle joint to the metatarsal; and 4 scores: severe edema and redness, from the ankle to the whole instep and toes, or ankylosis of the ankle or wrist joints). The scores for the four limbs of each mouse were added together and the highest score was 16 (4×4).

According to their arthritis scores, 5 to 7 mice were assigned to each group of three groups, one model control group and two administration groups. Treatment stars when the average arthritis severity scores in each group were about 1-2. Two doses of 3 mg/kg and 10 mg/kg were designed and orally administrated once a day for 14 days. At the same time, a normal control group was established. The results from the test groups were compared with the results of the normal control group and the model control group, so as to determine the therapeutic effect of the test compounds on arthritis in the model.

By comparison of the arthritis severity scores, compound 132 of the present invention was confirmed to have a good therapeutic effect on arthritis in the CIA model at the designed doses in a dose dependent manner.

The results are shown in FIG. 2.

Test Example 6 Adjuvant-Induced Arthritis (AIA) Model in Rats

100 mg of inactivated Mycobacterium tuberculosis (purchased from BD Difco, No.: 231141) accurately weighed and dissolved in 5 mL of incomplete Freund's adjuvant (IFA) (purchased from Sigma, No.: F5506), and then with 5 mL of physiological saline added, was homogeneously emulsified into 10 mg/mL of complete Freund's adjuvant (CFA). In order to induce the AIA model in rats, 50 Lewis rats in SPF grade (purchased from BeijingVital River Laboratories (VRL), animal production license number: SCXK (Beijing) 2012-0001), male, weighing 180-200 g, and adaptively feeding for 7 days, were injected with the complete Freund's adjuvant containing the inactivated Mycobacterium tuberculosis (H37RA, 10 mg/ml) at a dose of 0.1 ml/rat at the dorsal base of the tail to induce arthritis in rats. At the same time, three non-immunized rats were used as a normal control group. Rats were evaluated for the severity of arthritis using an established scoring system ranging from 0 to 4 as follows: 0=no evidence of erythema or swelling; 1=slight erythema or swelling of one of the toe joints; 2=erythema or swelling of more than one toe; 3=swelling of the ankle or wrist joint; 4=swelling of all toes including the ankle joint. All four paws of the rat were scored individually, and the highest score was 16.

The paw volumes of the rats were measured by the drainage method using a plethysmometer (Plethysmometer PV-200, Chengdu Taimeng Science and Technology Co., Ltd.) to determine the volumes below the ankle joints (in mL). The rats were measured for paw volumes every other day from day 10 after primary immunization, i.e. day 1 of the administration. The volumes of the four limbs of each rat were added together, and then divided by 4 to give an average value. Two doses of 30 mg/kg and 100 mg/kg were designed and orally administrated once a day for 7 days. At the same time, a normal control group and a model control group were established, and the results from the test groups were compared with the results from the normal control group and the model control group, so as to determine the therapeutic effect of the test compounds on arthritis in the model.

By comparison of the arthritis severity scores, compound 132 of the present invention was confirmed to have a good therapeutic effect on arthritis in the AIA model at the designed doses.

The results are shown in FIG. 3.
